Double Glazing Repairs
If your double glazed windows are becoming difficult to open or are showing signs of condensation it could be time to make repairs. This is usually done without the need to replace the whole window unit.
The process of fixing your own double glazing will require specialized tools, which is why this is normally better left to professionals.
Condensation
The sight of condensation in your double glazing isn't just annoying, it also means that warm air is escaping your home. This is usually the indication of a damaged seal or deterioration. If this is the case, it's best to have the entire window replaced.
In some instances you may be able to use a hairdryer (from a safe distance) to remove the moisture between the glass panes. This is a quick fix, but it's worth keeping in mind that you should seek professional help whenever you can, as the longer this issue continues for a long time, the more damage it will cause to the double glazing, and possibly to your health as well.
If the condensation is limited to a tiny portion of your window frame it is usually possible to eliminate it by wiping it away regularly and quickly. If you see condensation over a larger portion of the window frame, it could mean that the seal has been damaged and the windows are less thermally efficient.
Internal condensation can be caused by a variety of reasons but is usually due to excessive humidity and/or inadequate ventilation around the house. Double-glazed windows tend to show more condensation than older single pane windows because humidity can easily form droplets of water on cold surfaces. Install a vent in your bathroom or kitchen if it is extremely humid.
If your windows remain in the warranty period and you want to contact the company that installed them to describe the issue and ask them to rectify the issue for you. They might be able to replace the unit or they may need to install air vents that are one-way to stop any further condensation. This is a better option than replacing your double-glazed windows as you will save time and money.
Foggy Glass
Foggy windows can be an indication of a failing seal in double-pane windows. Double-pane windows are made up of two glass panes with a space between them. This space is filled with energy efficient gasses like Krypton or argon. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. If the seal fails it is possible that moisture will seep in and cause fog. Foggy windows can make your home less efficient and unattractive.
While double glazing repair can replace your windows when they're leaking, many homeowners prefer to hire an expert for window repair instead. A glass expert can help determine if the windows are able to be fixed before making recommendations. If they need to be replaced, a glass expert will be able to provide high-quality replacements that are not prone to fogging.
Double glazing can also cause issues when it comes to the opening and closing of windows or doors. This can be caused by extreme weather conditions or changes to the structure of the frame. If you find that your double-glazed is difficult to open, a good first step is to speak to the business you purchased it from. The majority of companies offer warranties that provide their products for a specified period of time, and some even offer lifetime guarantees.
If you are unable to solve the issue with your current provider, it might be time to change providers. Always ask for a written confirmation of your complaint, as well as any agreements that were made, and the dates. If you need to switch providers, this will make it easier.
Foggy windows can be repaired by defogging, a procedure that involves drilling holes in the window, infusing cleaning solution, removing the soiled liquid, and drying the inside of the glass. This is a relatively new method, and it's worth considering whether it's suitable for your home before committing to it. It won't, however, restore the energy efficiency that has been lost due deterioration of seals.
Cracked Panes
A crack in a double-glazed window might seem like a minor issue however it could cause significant damage. It is crucial to get the crack fixed as quickly as you can to prevent further damage, particularly if it's on inside of the glass.
Double-pane windows are made up of two glass panes joined with a space in between that is filled with an inert gas such as argon or krypton. This is to ensure that the heat from your home isn't transferred through the glass. The gas also slows down the transfer of heat so that the warm air in your home can move slowly through the window than it would if there was nothing between the two panes of glass.
When the windows are installed, it is crucial that the windows are fitted correctly and have a top-quality seal. A licensed glazier should be able to install the windows, as they'll be able to seal them securely to ensure maximum insulation. If the seal on the window is not working then the gas in the panes may leak out and decrease their insulation properties, leading to cracks between two panes.
Another reason that is commonly cited for cracked double-pane windows is due to poor installation, which can lead to the glass expanding and contracting at different rates. This can lead to stress cracks that appear over time and can weaken the glass. If this happens, seek out a glazier who can replace the broken glass with one that is better suited to your home.
If you notice a tiny crack in your double-glazed windows it is important to know that the crack can't be repaired by filling it with adhesive. Double-paned windows depend on an elongated seal between the two panes, and any cracks will only worsen as time passes.
It's essential to remember that handling broken glass is risky, so it's always best to get an experienced glazier who will have the right tools to complete the task. They'll also be able to take the old sealant from the glass without causing any further damage.
Leaking Seals
A double or triple-pane window comprises an insulated glass unit (IGU) comprising three or two sheets of annealed or tempered glass. The IGU is held together by a combination of polyurethane and spacers made from aluminum which creates an airtight seal between the windows, which prevents water from entering your home. Over time, the seal may be damaged and allow water to get in.
This is typically caused by the natural expansion or contraction of the materials that were used to create your window. The sealant (silicone or polyurethane) can shrink and stretch slightly with variations in temperature and humidity which can lead to IGUs being at risk of failure. If the seal is damaged the insulating fill gas could leak, leaving your windows with the appearance of fog and draughts that can reduce the efficiency of your home.
If a window seal fails it can also cause water or condensation to form between the panes that you are unable to wipe away. In some cases, moisture may leave a permanent stain on the window glass.
Typically, you can correct the problem by having your windows professionally cleaned and sealed. This procedure requires specialized equipment to eliminate moisture, fill the void with argon, or Krypton gas, and then seal it without letting the gas escape again. The price of this service may differ based on the type of IGU and your location, but most double-glazed windows can be repaired within an hour or two.
In addition to changing your window seals, there are a few other things you can do to increase the energy efficiency of your double-pane windows. First, try to choose windows that are energy efficient and have coatings that will reflect the sun's rays rather than absorb them. This will make your home cooler and more comfortable as well as enhance the appearance of your windows. Use caulk around your frame of the window to seal any gaps that could let cold air in and warm air out. In some instances it is a better alternative to replacing the whole window.
